[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0016] like Figures 1-3As shown, a plastic masterbatch drying device includes a material tank 1, a tank cover 2, a blower 3, and a hot air duct 4. The top of the material tank 1 is detachably connected to the tank cover 2, which has a feed inlet 21. The bottom of the material tank 1 is conical, with a discharge outlet 11 at the tip. A valve 12 is connected to the discharge outlet 11. One end of the hot air duct 4 penetrates the lower part of the material tank 1, and the other end of the hot air duct 4 is connected to the exhaust port of the blower 3. Both the blower 3 and the hot air duct 4 are... A uniform control unit is connected. A conical screen 6 is installed above the hot air duct 4 inside the material bucket 1. The tip of the screen 6 faces downwards, and a material outlet 61 is opened at the tip of the screen 6. A rotating cylinder 7 is longitudinally inserted inside the bucket cover 2. The rotating cylinder 7 is rotatably connected to the bucket cover 2 via bearings. Several stirring blades 71 are evenly distributed on the outer circumference of the rotating cylinder 7. A connecting rod 8 is longitudinally movable inside the rotating cylinder 7. A cover plate 9 is threadedly connected to the bottom of the connecting rod 8. A support is connected to the top of the bucket cover 2. A telescopic cylinder 110 is vertically mounted on the support 10. The telescopic cylinder 110 is a pneumatic cylinder. The top end of the connecting rod 8 is connected to the telescopic end of the telescopic cylinder 110. The telescopic cylinder 110 drives the cover plate 9 to rise and fall. When the cover plate 9 falls and contacts the screen 6, it can cover the material discharge port 61. A sealing bearing 120 is sleeved on the connecting rod 8. The inner ring of the sealing bearing 120 is welded to the connecting rod 8. A sealing rubber ring 121 is sleeved on the outer ring of the sealing bearing 120. The sealing rubber ring 121 abuts against the inner wall of the rotating drum 7. The sealing rubber ring 121 can prevent hot air or plastic particles from entering the rotating drum 7. A motor 130 is vertically mounted on the top of the drum cover 2. A drive gear 131 is fixedly connected to the main shaft of the motor 130. A driven gear 140 is fixedly sleeved on the top of the rotating drum 7. The drive gear 131 and the driven gear 140 mesh. The telescopic cylinder 110 and the motor 130 are both connected to the industrial control computer 5.
[0017] In actual use, plastic masterbatch is fed into the material barrel 1 through the feed port 21. The motor 130, the blower 3, and the hot air tube 4 are turned on. Hot air blows upward from the bottom of the material barrel 1, which can dry the plastic masterbatch in the material barrel 1. The motor 130 drives the rotating drum 7 to rotate. The stirring blades 71 on the rotating drum 7 can stir the plastic masterbatch. Stirring the plastic masterbatch while the hot air is drying it can effectively prevent the plastic masterbatch from clumping, make the plastic masterbatch heat more evenly, and improve the drying efficiency of the plastic masterbatch. After drying, the connecting rod 8 is pulled upward by the telescopic cylinder 110 to open the discharge port 61, which facilitates the rapid discharge of the dried plastic masterbatch.
[0018] In this embodiment, a number of ventilation holes are evenly arranged on the cover plate 9 to further increase the ventilation area and improve the drying efficiency.
